Agro-100, Ash Grove Cement agree to recycle kiln dust

Agro-100, Joliette, Quebec, and Ash Grove Cement have renewed their partnership of the past few years.

This will enable Agro-100 to provide a secure supply of kiln dust used, after a specialized screening process, by agricultural producers in Quebec and Ontario as an ecological alternative to fertilizer. This residual fertilizer material—a calcium amendment—is marketed under the brand name proKa.

Ash Grove Cement, Overland Park, Kansas, and Agro-100 executives were looking forward to this announcement with enthusiasm.

“We are pleased to be able to reassure our customers that the product will be available for the 2023 season and to maintain a remarkable environmental record,” says Agro-100 President Stéphane Beaucage.

Hundreds of thousands of metric tons of this dust material have been repurposed by Agro-100 for several years to produce a Bureau de normalisation du Québec-certified mineral fertilizer for agricultural land in Quebec and Ontario.

Beaucage says proKa is one of the innovative lime fertilizers in the company’s product line that is rich in calcium, potassium, sulfur, magnesium, and also in the micronutrients manganese, zinc, selenium and copper.

“Research results clearly indicate that proKa applications improve soil health by adding these valuable nutrients that are easily absorbed by plants,” says Beaucage, adding that soil amendment provides both lime and nutrients for the soil in a single application that saves time and money for agricultural producers.
